I just installed a trendnet wireless router. I have a gateway ml7632 laptop with vista os. My computer sees the connection and tells me the signal strength, but my comp will not connect. When I diagnose it tells me "wireless network connection" does not have a valid ip configuration. Help please. I have tried everything to correct this issue without success. I am very frustrated. I spent 75 minutes on phone with router manufact. Without resolution.

Post your IP configuration and router model. Both the router and the computer need to be configured to be on the same subnet. Typically the router will provide DHCP (http://en.wikipedia.org/wiki/Dhcp) service to the networks it is connected to so that any computers configured for DHCP will automatically be assigned proper addressing. Since the computer isn't receiving proper addressing either it or the router are not configured for DHCP. Alternatively, addressing can be assigned manually but to do that the addressing the router is currently using must be known or else the following addressing for a private lan configured which will work in most but not all situations:

Router:
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0

Computer:
IP Address: 192.168.1.2 (last number can be 2 through 254)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1 (the router)
